Description

  The present invention relates to a timepiece.

A watch is required to have a function as a practical product and a decorative property (aesthetic appearance) as a decorative product.
Conventionally, in order to obtain a high-quality appearance as a watch, a watch provided with a dial made of a metal material has been generally used. However, in a conventional watch, the range of appearance that can be expressed. However, it was not possible to meet the needs of consumers.
For example, there is a great need for a timepiece having a three-dimensional appearance, and a timepiece dial in which a plurality of patterns such as patterns and transparent coating films are alternately formed and laminated has been proposed (see Patent Document 1).

  However, a watch equipped with such a timepiece dial cannot express a three-dimensional effect that is greater than the thickness of the timepiece dial. Since it is difficult to make it extremely large, it has not been possible to sufficiently meet the above needs. In particular, in a portable timepiece such as a wristwatch, in particular, there is a great limitation on the thickness of the entire timepiece, and it has been extremely difficult to realize an appearance full of stereoscopic effect.

  As shown in FIG. 1, the second hand 103 is arranged on the glass plate 5 more than the minute hand 102. As shown in FIG. 1, a plate-like member 6 and a decorative layer (decorative plate) 7 are arranged in this order from the upper side between the solar cell 8 and the minute hand 102. The plate-like member (disk needle) 6 is fixed to an hour wheel as a shaft (rotating shaft) 91 provided in the movement. The decoration layer (decoration plate) 7 is supported by the support member 20 in a state of facing the solar cell 8. The support member 20 is sandwiched between the case 2 and the back cover 3.

The support member 20 has an annular shape, and is installed on the outer peripheral side of the solar cell 8 or the movement 9. The inner diameter of the support member 20 is sharply changed (increased) at two locations on the inner periphery thereof, and step portions 201 and 202 are formed at the respective locations.
The edge 73 of the decoration layer 7 is supported and fixed to the step 201 located on the upper side of the steps 201 and 202. The method for fixing the decoration layer 7 is not particularly limited. For example, adhesion (adhesion with an adhesive or a solvent) or a concave portion is provided on the outer periphery of the decoration layer 7 and tightened to the convex portion provided on the support member 20. For example, a method of fixing by cost.

  The upper end surface 203 of the support member 20 supports the edge 6131 of the lower surface (back surface) 613 of the plate-like member 6 (microlens layer 61). As will be described later, the plate-like member 6 is rotatable, and when the plate-like member 6 rotates, the edge portion 6131 slides on the upper end surface 203. The upper end surface 203 is preferably provided with a lubricant. Thereby, the sliding resistance (friction resistance) at the time of the plate-shaped member 6 rotating can be reduced. As the lubricant, for example, silicone, silicone oil, grease, various oils, surfactants and the like are used. If the edge portion 6131 is configured not to slide on the upper end surface 203, it can be configured without using a lubricant.

As described above, in the present embodiment, the decoration layer 7 is fixed, and the microlens layer 61 is configured to be rotatable. Thereby, the appearance of the timepiece 1 can be easily changed with the rotation of the pointer (hour hand 62), and the change in the appearance can be suitably controlled.
Although it does not specifically limit as a constituent material of the support member 20, For example, the same constituent material as the back cover 3 can be used.

The plate-like member 6 (microlens layer 61) has a disk shape. The plate-like member 6 is disposed (supported) coaxially with the shaft 91 of the minute hand 102 and the second hand 103.
In addition, a disc-like decoration layer 7 is provided below the plate-like member 6, and when the plate-like member 6 or the decoration layer 7 is viewed in plan, the plate-like member 6 (microlens layer 61). And the decorative layer 7 overlap each other.

  The microlens layer 61 constituting the plate-like member 6 includes a plurality of microlenses 611. The microlens 611 is regularly formed when the plate-like member 6 (microlens layer 61) is viewed in plan view. It is arranged. The decoration layer 7 has a repeating pattern 71 regularly arranged when viewed in plan. The repeating pattern 71 is provided in the same kind of arrangement as the microlens 611 and at a different pitch from the microlens 611. As will be described in detail later, the microlens layer 61 (plate-like member 6) and the decoration layer 7 are configured to be relatively rotatable.

  In this way, by having a relatively rotatable microlens layer and a decorative layer, it is possible to provide a watch that visually uses light interference (moire) and exhibits a three-dimensional appearance, In particular, by utilizing the illusion of the observer, the thickness of the plate material (a plate-like member having a microlens layer and a decorative board) can be recognized by the observer as being more than the actual thickness, and the three-dimensional effect can be achieved. As a result of earnest research, the present inventor has found that an overflowing clock can be provided.

  Furthermore, the present inventor can change the appearance of the timepiece while making the microlens layer and the decorative layer relatively rotatable so that the three-dimensional appearance of the timepiece is excellent. Due to the change in the ratio between the pitch of the microlens and the pitch of the structural unit of the repetitive pattern accompanying the relative rotation, the sense of depth (three-dimensional effect) of the plate material (a plate member and a decorative plate provided with the microlens layer) It has been found that can be suitably changed.

Therefore, in the timepiece according to the present invention (a timepiece in which at least one of the hands of the analog timepiece is constituted by a disk hand), a microlens layer in which a plurality of microlenses are regularly arranged when viewed in plan, And a decorative layer provided with a repetitive pattern having a pitch different from that of the microlens, and when the microlens layer or the decorative layer is viewed in plan, The decoration layer overlaps, and the microlens layer and the decoration layer are configured to be relatively rotatable.
In the timepiece according to the present invention, the plate-like member having the microlens layer constitutes a disc hand. Thereby, the relative positional relationship between the microlens layer constituting the plate-like member and the repetitive pattern constituting the decoration layer changes with time, and the appearance of the timepiece changes accordingly.

Hereinafter, the plate-like member 6 and the decoration layer 7 will be described in detail.
The plate-like member 6 has a microlens layer 61 and an hour hand (printing unit) 62.
An hour hand (printing unit) 62 is provided on the upper surface (front surface) 612 of the microlens layer 61. Thereby, the time can be confirmed.

Colorants such as various pigments and various dyes may be used. Among these, as the constituent material of the hour hand 62, a metal material is preferable because of its excellent aesthetic appearance.

The microlens layer 61 has a plurality of microlenses 611 arranged regularly.
The plate-like member 6 having the microlens layer 61 is rotatable, and the relative positional relationship between the microlens 611 constituting the microlens layer 61 and the repeated pattern 71 of the decoration layer 7 is the same as that of the plate-like member 6. It can be changed by rotation. Thereby, the timepiece 1 can be arbitrarily set to the state shown in FIG. 2 or FIG. Then, by changing the relative positional relationship between the microlens 611 and the repeated pattern 71, the appearance of the timepiece 1 can be changed, and in particular, the depth feeling of the timepiece 1 can be suitably changed. In particular, in the present embodiment, the appearance of the timepiece 1 can be changed with the movement of the hour hand 62, that is, with the passage of time.

In the present invention, “having light transmittance” means having a property of transmitting at least part of light in the visible light region (wavelength region of 380 to 780 nm), and preferably transmitting light in the visible light region. The rate is 50% or more, and more preferably the light transmittance in the visible light region is 60% or more. For example, a white fluorescent lamp (manufactured by Toshiba Corp., inspection fluorescent lamp FL20S-D65) is used as a light source, and such a light transmittance is a solar cell (solar shape) having the same shape as the member to be measured under 1000 lux. Current value (Y) when power is generated in the same state as described above, except that a member to be measured is placed on the light source side surface of the solar cell, relative to the current value (X) when power is generated by only the battery) The ratio ((Y / X) × 100 [%]) can be adopted. Hereinafter, unless otherwise specified, in this specification, “light transmittance” refers to a value obtained under such conditions.

  Examples of the material constituting the microlens layer 61 include various plastic materials and various glass materials. The microlens layer 61 is preferably composed mainly of a plastic material. The plastic material is generally excellent in moldability (freedom of molding), and can be suitably applied to the production of the plate-like member 6 having various shapes. Further, if the microlens layer 61 is made of a plastic material, it is advantageous for reducing the manufacturing cost of the timepiece 1. In addition, since plastic materials are generally excellent in light (visible light) transmission and radio wave transmission, if the microlens layer 61 is made of a plastic material, a solar watch ( A timepiece having a solar cell) and a radio timepiece can be preferably applied. In the following description, an example in which the microlens layer 61 is mainly made of a plastic material will be mainly described.
